Sizwa kanjani? Isimanga sendlebe kanye nohambo lomsindo (Uhlelo Lokuzwa)

Wake wema wacabanga ngendlela izingoma esizilalela nsuku zonke, amazwi esiwakhuluma nabangani bethu, imisindo emnandi yezinyoni, njalo njalo, ezingena ngayo ezindlebeni zethu futhi ziqondwe ubuchopho bethu? Kuyinqubo emangalisayo neyinkimbinkimbi ngempela. Kufana nomlingo! Ngakho-ke, namuhla sizokhuluma ngendlela izindlebe zethu eziyigugu ezisebenza ngayo, ngendlela elula kakhulu, njengokutshela umngane.

Umsebenzi omkhulu wesitho esincane esibizwa ngokuthi indlebe

Izindlebe zethu zingahlukaniswa zibe izingxenye ezintathu eziyinhloko, njengamakamelo endlini. Lezi yizi:

1. Indlebe Yangaphandle

2. Indlebe Ephakathi

3. Indlebe Yangaphakathi

Ingxenye ngayinye inomsebenzi wayo othize, njengoba umsindo uhamba uye ebuchosheni bethu. Ake sibone ukuthi lokho kwenzeka kanjani.

1. Indlebe Yangaphandle: Isango lokungena emsindweni

Uma ucabanga ngendlebe, yini efika engqondweni kuqala yingxenye ebonakalayo ngaphandle? Yilokho esikubiza ngokuthi i-pinna (ngokwezokwelapha ebizwa ngokuthi `(Pinna)`). Ukuma kwale pinna kuklanyelwe ngqo ukuqoqa amaza omsindo endaweni ezungezile nokuwaqondisa endlebeni. Kufana nokuqoqa izimpawu ezivela ku-`Satellite Dish`.

Cabanga nje, uma ukhuluma nomngane, amaza omsindo wezwi lakho ahamba emoyeni bese eshaya i-eardrum yomuntu olalele futhi oqoqayo.

Amaza omsindo aqoqwe yi-eardrum abese ehamba ngesakhiwo esincane esifana ne-tube esibizwa ngokuthi i-ear canal . Umsindo uhamba ngaleli payipi uye ekuqaleni kwendlebe ephakathi. I-ear canal inezakhiwo ezincane ezifana nezinwele kanye nezindlala ezikhiqiza i-earwax. Lokhu kuvikela indlebe othulini, ezinambuzaneni ezincane, nakwezinye izinto.

2. Indlebe Ephakathi: Lapho umsindo ukhuliswa khona

Ekugcineni kwepayipi lokuzwa kukhona ulwelwesi oluthambile kakhulu noluncane. Yi -eardrum (noma i-'Tympanic Membrane`) esiyaziyo sonke. Ifana nesikhumba sesigubhu. Lapho amaza omsindo avela ngaphandle eshaya le-eardrum, iqala ukudlidliza .

Manje umsebenzi wangempela uqala. Kunamathele kule ndlebe kukhona amathambo amathathu amancane kakhulu emzimbeni wethu. Mancane kakhulu, kodwa enza umsebenzi omkhulu. Lawa mathambo amathathu avame ukubizwa ngokuthi `(ama-Ossicles)`. Amagama awo yilawa:

• I-Malleus - Lokhu kufana nesando, esinamathele ku-eardrum.
• I-Incus - Leli yithambo eliphakathi nendawo, elixhunywe ku-eardrum kanye ne-auricle.
• I-Stapes - Leli yithambo elincane kunazo zonke emzimbeni. Lime njenge-horseshoe.

Uma i-eardrum idlidliza, ukudlidliza kuqala kuya kuma-ossicles, bese kuba yi-stapes, bese kuba yi-auricle. Lawa mathambo amathathu axhumene, esebenza njengohlelo lwe-lever encane, ekhulisa ukudlidliza okuvela ku-eardrum.Ithunyelwa endlebeni engaphakathi. Lokhu kukhulisa kubaluleke kakhulu, ngoba indlebe engaphakathi iqukethe uketshezi. Ukuze ukudlidliza okuza emoyeni kudluliselwe ngoketshezi, kufanele kube namandla.

Kukhona enye into ebaluleke kakhulu endlebeni ephakathi. Leyo yi -Eustachian Tube . Lena yipayipi elincane nje elixhunywe ngemuva komphimbo wethu. Wake wazizwa sengathi izindlebe zakho ziyakhala lapho ukhuphuka intaba noma undiza ngendiza, bese uvuka ngokuzumayo ngomsindo ongavamile 'wokuchofoza'? Yilokho okwenziwa yileli payipi le-Eustachian ngaleso sikhathi. Lapho sivula imilomo yethu futhi sigwinya, leli payipi liyavuleka futhi livale ukuze lilinganise umfutho womoya kuzo zombili izinhlangothi ze-eardrum. Yilapho i-eardrum ingadlidliza ngokukhululeka nangokufanele.

3. Indlebe Yangaphakathi: Lapho umsindo uguqulwa ube izimpawu zikagesi

Ama-stape, ekugcineni kwendlebe ephakathi, axhumeka esithweni esincane endlebeni engaphakathi esifana negobolondo lomnenke. Sibizwa ngokuthi i-cochlea . Ngaphakathi kukhona uketshezi olukhethekile kanye nezinkulungwane zezakhiwo ezinhle kakhulu ezifana nezinwele ezibizwa ngamaseli ezinwele .

Lapho amagagasi okudlidliza akhulisiwe (`Ukudlidliza`) avela endlebeni ephakathi edlula oketshezini olungaphakathi kwe-cochlea, lawo maseli ezinwele ayashukunyiswa. Njengoba nje igagasi lidlula emanzini, izitshalo emanzini ziyanyakaza. Lapho la maseli ezinwele ehamba, kwenzeka into emangalisayo: ukuthi ukudlidliza komshini (`Ukudlidliza Komshini`) kuba izimpawu zikagesi (`Izimpawu Zikagesi` noma `Iziphazamiso Zezinzwa`)!

Amaseli ezinwele ngaphakathi kwe-cochlea akhethekile kakhulu. Afika ngobude obuhlukene, njengezihluthulelo zepiyano. Njengoba nje ukhiye ngamunye ukhiqiza umsindo ohlukile, lawa maseli ezinwele nawo ayazwela kumaza ahlukene. Okusho ukuthi, iqembu elilodwa lisabela emisindweni ephezulu (njengomsindo wokutshiyoza) kanti elinye iqembu liyasabela emisindweni ephansi (njengomsindo wesigubhu). Ingabe lo mklamo awumangalisi?

Ngaphezu kokuzwa, indlebe yangaphakathi nayo inengxenye elawula ibhalansi yethu (`i-Vestibular System`). Kodwa njengoba sikhuluma ngokuzwa namuhla, sizoxoxa ngalokho ngokuningiliziwe kamuva.

Uhambo lomsindo oluya ebuchosheni kanye nokuqonda kwawo

Manje sekuza ingxenye ebalulekile. Izimpawu zikagesi ezikhiqizwa yilawo maseli ezinwele ziya ngqo ebuchosheni bethu ngenzwa ekhethekile ebizwa ngokuthi i-'Auditory Nerve' . Ubuchopho bunesikhungo esikhethekile esizinikele ekuzweni (i-'Auditory Cortex').

Ubuchopho buhlaziya lezi zimpawu zikagesi ezingenayo futhi businika ikhono lokuqonda izinto ezinjengokuthi, 'O, leli yizwi likamama,' 'Lena yingoma engiyithandayo,' 'Kukhona inja ekhonkotha ngaphandle, angazi ukuthi kukhona okungahambi kahle.' Cabanga nje, konke lokhu kwenzeka ngemizuzwana embalwa, ngesikhathi esifushane kakhulu!

Akukhona lokho kuphela, ngoba sinezindlebe ezimbili, ubuchopho bungakwazi futhi ukuthola ukuthi umsindo uvela ngakuphi. Bunquma ukuthi umsindo uzwakala uphakeme kancane noma uthambile kancane endlebeni eyodwa.

Kungani kubaluleke kangaka kithi ukuzwa?

Lokhu akuyona into engavamile ukuyisho.

• Ukuxhumana: Sixhumana nabanye futhi siyaqonda ukuthi bathini ngokulalela.
• Ukufunda: Ukulalela kubalulekile lapho ufunda okuthile okusha, kungaba esikoleni noma emsebenzini.
• Ukuzijabulisa: Ukulalela ingoma emnandi kukwenza ujabule, ujabulele ingxoxo ebhayisikobho, futhi uzole ngokulalela imisindo emnandi yemvelo (izinyoni zicula, izimpophoma) kumayelana nokulalela.
• Ukuphepha: Uma sizwa umsindo wemoto isondela ngesikhathi sisemgwaqweni, siyasindiswa engozini, futhi uma kukhona umlilo endlini yethu, sixwayiswa umsindo we-"Fire Alarm". Ngenxa yakho konke lokhu, ukusebenza kahle kwezindlebe zethu kubaluleke kakhulu.

Ungazinakekela kanjani izindlebe zakho?

Kudingeka sinakekele izindlebe zethu, eziyigugu futhi eziyinkimbinkimbi, akunjalo? Uma sinakekela izinto ezincane, singagcina ukuzwa kwethu kukuhle isikhathi eside.

• Gwema imisindo ephezulu: Akukuhle ukulalela umculo ngevolumu ephezulu noma ukulalela ama-headphone ngevolumu ephezulu isikhathi eside . Uma usebenza ezindaweni ezinomsindo ophezulu, njengezimboni noma izindawo zokwakha, gqoka izivikelo zendlebe. Ngoba ukuchayeka isikhathi eside emisindweni ephezulu kungalimaza amangqamuzana ezinwele athambile esikhulume ngawo, okubangela ukulahlekelwa ukuzwa unomphela.
• Ungazifaki izinto ezindlebeni zakho: Ungazifaki izinto ezibukhali njengezinti, ama-cotton bud, okhiye, noma amaphini ezindlebeni zakho ukuze uzihlanze. Ukwenza kanjalo kungacindezela i-earwax ngaphakathi futhi kulimaze umsele wendlebe noma i-eardrum. I-Earwax ivame ukuphuma yodwa. Uma ungakhululeki kakhulu noma uzizwa sengathi indlebe yakho ivaliwe, bheka udokotela ukuze uthole iseluleko.
• Gcina izindlebe zakho zomile: Abanye abantu bangase babe nezifo (isib. i-Otitis Externa noma i-Swimmer's Ear) uma amanzi engena ezindlebeni zabo ngesikhathi begeza noma bebhukuda. Kungcono ngabantu abanjalo ukusebenzisa ama-earplugs. Ngemva kokugeza, sula kancane i-earlobe kanye nengxenye engaphandle ezungeze indlebe bese uyigcina yomile.
• Qaphela izifo zendlebe: Uma unesifo sendlebe, uketshezi oluphuma endlebeni yakho, ukulahlekelwa ukuzwa, ukukhala njalo ezindlebeni zakho (`tinnitus`), noma isiyezi, ungazinaki. Bona udokotela ngokushesha bese uthola ukwelashwa. Ezinye izifo zendlebe ephakathi (`Otitis Media`) zingaba zimbi kakhulu uma zingelashwanga kahle.
• Ukuhlolwa okufanele kwezokwelapha: Ezinye izimo zezokwelapha ezifana ne-Diabetes Mellitus kanye ne-Hypertension zingathinta ukuzwa. Futhi, eminye imithi (izidakamizwa ze-Ototoxic) ingaba yingozi ezindlebeni. Ngakho-ke, uma unezimo ezinjalo zezokwelapha, gcina ukulawula okufanele futhi ulandele imiyalelo kadokotela wakho.

Ngamafuphi (Umyalezo Wokuya Ekhaya)

Kulungile, ngakho-ke sesikhulume kakhulu namuhla, akunjalo? Kalula nje, izindlebe zethu ziyisitho esiyinkimbinkimbi kakhulu nesisebenza kahle ngendlela emangalisayo.

Amaza omsindo aqoqwa yindlebe yangaphandle, akhuliswe yindlebe ephakathi, aguqulwe abe izimpawu zikagesi endlebeni yangaphakathi, bese edluliselwa ebuchosheni ngenzwa yokuzwa. Lena yindlela esiqaphela, sijabulele futhi siqonde ngayo imisindo ehlukahlukene kuleli zwe.

Cishe usuyaqonda manje ukuthi leli khono elimangalisayo libaluleke kangakanani kithi empilweni. Ngakho-ke, nakekela izindlebe zakho futhi uzivikele. Ngoba, ukuzwa kahle kubaluleke kakhulu empilweni enempilo nejabulisayo. Uma uneminye imibuzo ngalokhu, ungesabi ukukhuluma nodokotela.
